We have an old Glow worm fuel save F boiler, everything seems to work ok. but if the CH and HW is set to off the boiler will light up for say 2-5mins then turn off. If the dial on the front of the boiler is turned from say 4 to 2 it will stop the process for a short while.
None of the rads are getting hot but the cupboard the hot water tank is in is cooking. I have check the micro valves and made sure these are working okay so little unsure why it keeps heating the water.
cheers
